Duff reunited with Lizzie McGuire costars Lalaine (a.k.a. best pal Miranda) and Jake Thomas, who played Lizzie's little brother, on Monday night. Thomas shared a photo of the crew on Instagram with the caption, "So this happened last night." Oh, how these youngsters have grown.

Bowling with the cast of Lizzie McGuire sounds fairly epic, but we've got a question. Wasn't Duff meant to go bowling with her first-ever Tinder date last night? Is she signing up for a few extra frames to perfect her game? Is she using Miranda and Matt as chaperones? Is this date not actually happening? Or, is she just really, really into bowling? Girl, we need to talk.
